FUSE BLOCK FOR AUTOMOBILES Filed April 14, 1950 INVENTOR Patented June 21, 1932 UNITED STATES PATENT OFFICE rusn BLOCK non Auromosrnns Application filed April 14,

This invention relates to fuse blocks and fuses for automobiles and deals particularly with a block having special characteristics for mounting upon a certain make of auto 6 mobile.

The objection has been raised with refer ence to a particular make of automobile, namely: the Model A Ford, that no provision has been made to install a fuse in the circuit that includes the lights, the horn, and the lighting switch. It is therefore an object of this invention to provide a fuse in a car of this make and to provide means for mounting the fuse upon the car in a plainly visible and readily accessible place. In so doing I take advantage of the structural characteristics of the aforesaid automobile.

The construction of the generator and the relay switch in the automobile just mentioned afford an excellent means for mounting a fuse block of the character described. In this respect, the manufacturer mounted the relay switch upon the generator and left a small space between the two and in order to make the relay demountable it is provided with legs that are attachable to the generator casing. Recognizing the need of a fuse in the organization just described I conceived the idea of mounting a fuse block on the generator by utilizing the aforementioned space and leg. The addition of a fuse at this point yields the advantages of being easily visible in case of trouble and readily accessible for replacement. It is also an ideal place for installing fuses on used models in that the circuit is already broken at this point and provided with terminal clips, which necessitates onlythe transferring of one terminal to a binding post on the fuse block and the insertion of a bus bar be,

parent that I have taken advantage of existing structural details to provide an improvement in an existing organization.

Other features and advantages will become apparent as the description proceeds in connection with the drawing in which 1- Fig. 1 is a fragmentary view showing my fuse and fuse block as they would appear in place on the generator of a Model A Ford automobile,

Fig. 2 is a plan view of my fuse and fuse block as it appears before mounting,

Fig. 3 is a side elevation of the same,

Fig. 4 is plan view of another form of fuse block adapted for a double mounting on the 55 generator and,

Fig. 5 is a view showing the relay switch detached from the generator.

- Referring to the drawing and particularly to Fig. 2 my device is seen to comprise a plate 11 which is formed of suitable insulating material and which is provided with an inwardly extending curved slot 12 on the upper side thereof. A small hole 13 is formed in the plate 11 in close proximity to the slot 12, the purpose of which will be explained later. A pair of fuse clips designated 1 1 and 15 respectively hold a conventional fuse 16 and screws '17 and 18 respectively form binding posts for said clips. I

In mounting the plate 11 I take advantage of a structural detail of the generator and. relay switch mounting inthe make of car aforementioned. As shown in Fig. 1 a relay I switch A is mounted upon a generator B. The mounting of the relay is accomplished by means of legs 19 formed on the relay casing, which legs are provided with open ended slots 20. The slots 20 are adapted to receive a screw 21 which is screwed into thegeneratorcasing. The legs 19 extend a short distance below the shell before bending to conform to the shape of the generator as shown at 22 and I utilize this straight portion and the screw 21 to mount my fuse block. p

In mounting my device the screw 21 is first removed and the block 11 is brought into position in the following manner: the slot 12 in the plate 11 is slipped over the straight portion 22 of the leg 19 and the hole 13 in the plate 11 is brought into registration with the screw hole from which the screw 21 has been extracted. The screw 21 is then inserted and screwed down to a tight fit. The plate 11 is thus clamped securely in position. In order to complete the circuit through the fuse, the terminal clip 23 is removed from the binding post 24 and connected to the post 18 on the fuse block and a bus bar 25 is used to connect the post 17 with the post 24. With the fuse 16 in place the circuit is complete. The installation of the fuse block is accomplished in a short space of time and without disturbing any other part of the mechanism. There is no drilling of holes, marring of finished parts, soldering of joints nor any addition of terminal clips since the old elements are utilized.

In some cases the relay switch may be mounted upon the generator with the slots- 20 in the legs 19 extending in a reverse direction, therefore, in order to provide a complete mounting for all occasions I have provided a plate 26 with a double slot arrangement as shown at 12 and 12 and equipped with a double hole arrangement as shown at 13 and 13, in all other respects the plate 26 is identical with the plate 11.

Although this description has been direct- 30 ed primarily toward a specific construction of a fuse block for a special purpose I nevertheless intend that this disclosure shall include all forms of fuses and fuse blocks which are capable of being mounted in the manner described.

I claim 1. For use with a generator having a detachable screw mounted thereon the combination of; a demountable relay switch having an extending leg adapted to be secured to said generator by said screw; a fuse block having a slot adapted to engage said leg and a hole in said block arranged to utilize said screw to secure said block to said generator when said leg and said slot are engaged.

2. F or use with a generator having a relay switch mounted thereon by means of a' screw threaded member inserted into a screw n threaded hole in said generator; a fuse block having a slot adapted to slidably engage a portion of said relay and a hole adapted to receive said screw threaded member.

3. In combination with a relay switch having legs adapted to be secured to a generator 0 by means of a screw threaded member; a

fuse bloc-k adapted to be mounted upon said generator, said fuse block having a slot arranged to engage a leg of said relay and a gole adapted to receive said threaded meni- In testimony whereof I have hereunto aflixed my signature at Los Angeles, California, this fith-day of April, 1930.
